Alright guys. I'm in desperate need of some help. So my 04 6.0 powerstroke (early build) has a pretty bad skip to it. I do have a cylinder 3 contribution code but I changed the injector but no luck. So one day on my way to work going down a hill I hit my tow:haul button. So going down the hill it was downshifting and doing its thing and got to the bottom of the hill and bam.,, runs perfect. Weird. So my next day to work It was skipping the whole way until the hill. Then after the tow button again I got to the bottom of the hill and took off and runs perfect again. So do I have a bad hpop? Or icp or something. All I can think of is when it's downshifting it's bringing the Rpms up the whole way down the hill and it's building oil pressure. Any help would be much appreciated

You can check the ICP by simply unplugging it. The truck will default to a preset parameter.
